Abstract

Fluid particulate solids process unit comprising: a main fluidized bed vessel with particulate solids; a withdrawal well spaced from said main fluidized bed vessel; a downwardly inclined standpipe having its upper end fluidly connected to said fluidized bed, and its lower end fluidly connected to said particulate solids withdrawal well; a standpipe for receiving particulate solids from said particulate solids withdrawal well, said standpipe having an open upper end fluidly connected to said particulate solids withdrawal well, wherein the particulate solids withdrawal well is provided with a closed lower end (floor), through which lower end an inlet portion of said standpipe extends into said particulate solids withdrawal well from below for receiving and transporting said particulate solids from said particulate solids withdrawal well, said extended standpipe inlet portion including an open upper end and a plurality of openings cut through the wall of said extended standpipe below said open upper end and above the closed lower end (floor) of said particulate solids withdrawal well.
